P0075 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The P0075 error code is related to Intake Valve Control Solenoid Circuit (Bank 1). This trouble code varies from one manufacturer to another, but it is general powertrain fault code for 1996 as well as of new car these days with Variable Valve Timing which would operate normally with oil pressure and is controlled by the camshaft position solenoid on engine bank 1. This fault code is related to the solenoid and electrical circuit.

The oil pressure and an electrical solenoid is used by the Intake Valve Control Solenoid to control the position of the exhaust valve. The vehicles which are new are equipped with variable valve timing. Now this would allow the engine control module or the PCM to adjust the opening as well as closing of the exhaust valve so that it can improve the fuel consumption while it is still providing the performance which has been requested by the driver. Now when the PCM would determine that there is some issue with the signal from the Intake Valve Control Solenoid

What causes this problem with the Intake Valve Control Solenoid Circuit B1?

• There can be a bad wire harness connection or the terminals might be corroded
• There can be some faults in the control solenoid
• Issues of short to power
• Short to ground
• There can be some defects in the engine control module
• Defects in the intake valve control solenoid bank
• 1 Intake Valve Control Solenoid Circuit Bank 1 harness may be opened or shorted
• There can be poor electrical connection intake valve control solenoid Circuit Bank 1 circuit

1. Boost pressure sensor - A faulty boost control solenoid can be troublesome. You can always rely on us as we have best auto parts for our customers.
2. Turbocharger - P0075 code can display due to faulty Turbocharger. So it is very important to replace the Turbocharger with us at equitable prices.
3. Supercharger - Do you remember when was the last time you got your Supercharger repaired? A defected Supercharger can cause a lot of issues like displaying P0075 code.
4. Knock sensor - Poor Knock sensor can cause a lot of difficulties, so why not get it replaced at time?
5. Spark Plug - Are there some faults in your Spark Plug? Don’t waste time and get them replaced or else P0075 code can turn up.
6. Intake manifold - OBD Code P0075 can appear because of faulty Intake manifold. Get it replaced from us at equitable prices.
7. Boost Pressure Gauge - Everything is fine with turbocharger/supercharger and still P0075 code triggering? Then you must get your Boost Pressure Gauge checked.
8. Powertrain Control Module - It is an important auto part which needs full care. A faulty PCM can be a reason behind the flashing up of P0075 code.
9. Engine Control Module - Common cause behind this P0075 error code can be some fault in Engine Control Module. So it will be a good decision to replace them now.
10. Wastegate - There can be some issues with the waste gate due to which you may see P0075 code appearing over and over again. Visit us to buy best quality waste gate online.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P0075 code by mentioning some major symptoms below:

Common Symptoms

If there is a defective intake valve control, then it can cause the engine intake valves to not change the lift to them and will ultimately lead to an engine imbalance from bank to bank, which would cause the engine to run rough, hesitate, surge and possibly stall. The check engine light will start illuminating on once the engine control module detects the failure in the intake valve control circuit.

More air is forced into the engine with the help of turbochargers and then the engine is capable of working under normal aspirated conditions. The higher the volume of air forced into the cylinders in addition to the increased fuel equals greater power.

• The code P0075 would start triggering up because there can be some problem which is existing somewhere within this circuit preventing proper boost control. Additional codes in progression may be set regarding this malfunction, each of which pertains to a section of the circuit
• There can be lack engine acceleration
• The boost pressure gauge may start indicating less than 9 pounds of boost or it can exceed over 14 pounds of boost. Both of them would be out of range
• There can be unusual whining noises or rattling which may be coming from the turbocharger or piping
• Engine knock sensor code may start appearing indicating detonation is occurring due to high cylinder head temperatures
• There can be an overall lack of power in the car engine
• Smoke may start coming out from the exhaust
• There can be fouled spark plugs
• Engine temperature may become unusually high at cruise speeds
• There can be some hissing noises at the waste gate

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of aem intake, shift solenoid, engine manifold and a lot more. We are sure that now all your issues would be resolved.

An oil pressure as well as an electrical solenoid is used by the Intake Valve Control Solenoid to control the position of the exhaust valve. The vehicles which are new are well equipped with variable valve timing. It would allow the engine control module to adjust the opening as well as closing of the exhaust valve, thus improving the overall fuel consumption and at the same time would provide the performance which is requested by the car driver. If the power control module determines that there is some sort of issue with the signal coming from the intake valve control solenoid, then the powertrain control module would set the P0075 code.

• The overall engine performance may start decreasing
• The car engine may not start properly
• There can be an increase in the fuel consumption
